Smyrna, TN Building Safety: Electrical Permits (2026)

Title 12, Chapter 11 of the Smyrna Municipal Code adopts the National Electric Code, 2017 edition, and modifications to it, and calls the result "the electric code" (Section 12-1101). The edition is older than the 2024 editions the Town Council adopted for the building, energy, property maintenance, swimming pool and fuel gas codes in the same title, so an electrician in the Town of Smyrna, Tennessee works to the 2017 NEC text plus the local changes in Section 12-1102.

Those changes are specific. For Section 210.12 arc-fault circuit-interrupter protection in dwelling units, the town adds an exception: protection is not required in garages, laundry rooms, unfinished basements, bathrooms, outdoors, or for dedicated refrigeration outlets. Ovens and cooktop units installed as separate units are served by individual circuits. Service equipment of 225 amps or below has only one main means of disconnecting. Receptacles below the countertop at island or peninsular counter spaces are optional, and receptacles are not required in wall space behind a door that opens fully against a wall, with that space measured from the edge of the door when fully opened.

Inspection timing has its own rule. Only designated circuits are energized following a "service release" inspection, and that inspection is valid for 45 days from the date of inspection. For grounding a single family dwelling under Section 250.52, the code accepts either #4 copper securely attached to the rebar in the footing plus one additional driven ground rod, or a grounding electrode conductor of minimum #4 bare copper run unspliced in a trench no less than 20 feet long and 30 inches deep and encased in two inches of concrete.

Chapter 11 prints no permit fee or application steps. Permits sit with the codes enforcement and inspection division, which Section 12-903 charges with issuing and approving all building and occupancy permits. Appeals of the building official's decisions go to the Construction Board of Adjustments and Appeals under Chapter 10, on written notice filed within 30 calendar days after the decision.
